Drivetime intervals near water #180

Closed matias-piin closed 7 years ago

matias-piin commented 7 years ago

Hi, I'm finding that drivetimes generated near large bodies of water with multiple intervals cause some weird behavior. That is the intervals are not supersets of each other.

Example: https://galton.urbica.co/?&ll=-122.50264045111601,37.748018657001396&zoom=11.8&city=san-francisco&mode=car&page=cities&lang=en&center=11.8

When asking for a single interval (the larger one) it correctly returns a shape that would cover the smaller one, but when asked for all intervals at once you get these non-overlapping shapes.

Is there a way to fix this?

This issue should be closed now that Galton has the latest version of the isochrones library
